Operating Basics

6. If your CD/DVDs become dusty or dirty, wipe them with a clean dry

cloth. Wipe from the center out, do not wipe in a circular direction

around the CD/DVD. If necessary, use a cloth dampened in water or a

neutral cleaner. Do not use benzine, thinner or similar cleaner.

Floppy disks

1. Store your floppy disks in the container they came in to protect them

and keep them clean. If a floppy disk is dirty, do not use cleaning fluid.

Clean it with a soft damp cloth.

2. Do not slide back the floppy disk’s protective metal covering or touch

the floppy disk’s magnetic surface. Fingerprints may prevent the floppy

disk drive from reading data from the floppy disk.

3. Data may be lost if the floppy disk is twisted; bent; or exposed to direct

sunlight, extreme heat or cold.

4. Do not place heavy objects on your floppy disks.
5. Do not eat, smoke, or use erasers near your floppy disks. Foreign

particles inside the floppy disk’s jacket can damage the magnetic

surface.

6. Magnetic energy can destroy the data on your floppy disks. Keep your

floppy disks away from speakers, radios, television sets and other

sources of magnetic fields.

Sound System

Using the microphone

Your computer has a built-in microphone that can be used to record

monaural sounds into your applications. It can also be used to issue voice

commands to applications that support such functions.
Since your computer has a built-in microphone and speaker, “howling” may

be heard under certain conditions. Howling occurs when sound from the

speaker is picked up in the microphone and amplified back to the speaker,

which amplifies it again to the microphone.
This howling occurs repeatedly and causes a very loud, high-pitched noise.

It is a common phenomenon that occurs in any sound system when the

microphone input is output to the speaker (throughput) and the speaker

volume is too loud or too close to the microphone. You can control

throughput by adjusting the volume of your speaker or through the Mute

function.
To adjust the volume or activate Mute, click start, point to All Programs,

point to Accessories, point to Entertainment and click Volume Control.

In the Volume Control panel, you can use the slide bars to adjust the

volume level or click Mute at the bottom of the panel.
